Hyphen in image URL being stripped (images not showing any longer)

My site images are not showing. When opening image in a new tab, the URL to the image is missing the hyphen “/” between the domain name and the remainder of the image URL.

E.g. domain.comwp-content/uploads/2021/07/image.png
Should read domain.com/wp-content/uploads/2021/07/image.png

Any help on how I can fix this soonest would be sincerely appreciated!
